N2 - This paper presents a hierarchical chordal ring network topology (HCRN) as a regular logical topology for multihop WDM networks. In order to minimize the traffic increase and the transmission delay through the network due to packet relays or hops on intermediate nodes in the multihop network, the network topology is hierarchically constructed in HCRN, so that more lightpaths are assigned to connections between nearby nodes than those for distant nodes, while the maximum hop between any pair of nodes is restrained. This hierarchical topology is also beneficial to reduce the number of required wavelengths through increasing their reuses by multiple lightpaths, which is important for cost-conscious metropolitan area networks. Through comparisons on the network diameter and the number of required wavelengths with the original chordal ring network topology, we show the effectiveness of our proposed HCRN.
